Seeds for those interested. They're called trombettas and they're a climbing summer squash with everything you would expect there - nice, mild flavor, etc. They only have seeds in their 'head'. If you pick them young enough the seeds won't be formed so you can eat the entire thing. If you wait a bit longer, you can very easily scoop the seeds out and slice or stuff the head. Head to tail, these things can easily get over two feet. They can also be a bit curvy.
I've found them to be very hardy over the years. They climb really well without encouragement. The vines in the photo are easily 9 feet long.
You can indeed walk under the arch! You might bonk your head on a dangling gourd or squash though.
The love tap from your veggies is the best part though!
